摘要

背景：胫骨高位截骨术（HTO）对于治疗内侧室性膝骨关节炎至关重要。精确实现胫骨内侧近端角（MPTA）矫正和维持胫骨后坡（PTS）是临床成功的关键。本研究旨在比较3d打印患者专用器械（PSI）与传统HTO的使用，以实现精确的MPTA矫正和维持PTS，旨在提高HTO患者的手术效果。方法2018年9月至2021年7月104例HTO患者中，60例符合纳入标准，分为PSI组（30例）和常规方法组（30例）。放射学结果包括估计和术后MPTA值，以及术前和术后PTS测量。结果在常规HTO组中，估计的MPTA值与术后的MPTA值（94.3°±2.4°vs 93.5°±2.5°，P = 0.023）以及术前和术后的PTS值（8.8°±3.2°vs 7.9°±3.5°，P = 0.033）之间存在显著差异。相反，PSI组在这些值上没有表现出任何显著差异。结论使用psi引导下的HTO可以提高MPTA目标的准确性，提高PTS改变的预防效果。

Comparison of a patient-specific instrument and conventional high tibial Osteotomy: Accuracy of correction target and prevention of posterior tibial slope change

Background

High tibial osteotomy (HTO) is crucial for managing medial compartmental knee osteoarthritis. Precision in achieving the medial proximal tibial angle (MPTA) correction and maintenance of posterior tibial slope (PTS) is essential for clinical success. This study aims to compare the use of 3D-printed patient-specific instruments (PSI) to conventional HTO to achieve precise MPTA correction and maintenance of PTS, aiming to enhance surgical outcomes in HTO patients.

Methods

Among 104 patients who underwent HTO between September 2018 and July 2021, 60 met the inclusion criteria and were categorized into a PSI group (30 cases) and conventional method group (30 cases). Radiological outcomes included estimated and postoperative MPTA values, along with preoperative and postoperative PTS measurements.

Results

Within the conventional HTO group, significant differences were noted between the estimated and postoperative MPTA values (94.3° ± 2.4° vs. 93.5° ± 2.5°, P = 0.023), as well as between the preoperative and postoperative PTS values (8.8° ± 3.2° vs. 7.9° ± 3.5°, P = 0.033). Conversely, the PSI group did not exhibit any significant differences in these values.

Conclusion

This study indicated that the use of PSI-guided HTO could provide enhanced accuracy in achieving the target MPTA and improve the prevention of PTS changes.
